Unlock the full potential of your Mercedes-AMG G63 W463A with professional ECU remapping and performance tuning from Onyx Performance in Slough.
The Mercedes-AMG G63 is powered by a 4.0-litre V8 BiTurbo M177 petrol engine, producing a factory output of 585HP and 850Nm. Our performance tuning solutions are designed to optimise engine performance, improve throttle response and enhance the driving experience.
Mercedes-AMG G63 W463A Stage 1 Remap
Our Stage 1 ECU remap is designed to optimise the factory engine management software without requiring additional hardware modifications.

Benefits include:
- Increased horsepower for stronger overall performance.
- Increased torque for improved acceleration.
- Improved throttle response for a sharper driving experience.
- Stronger acceleration throughout the rev range.
- Improved in-gear performance for more effective overtaking.
- Smoother power delivery with optimised engine calibration.
All tuning is carried out with consideration for the vehicle’s mechanical condition and the requirements of its engine management system.
Mercedes-AMG G63 W463A Stage 2 Tuning
For owners looking for further performance, our Stage 2 tuning can be developed around suitable supporting hardware and a tailored ECU calibration.
With the appropriate supporting modifications, the supplied estimated Stage 2 figures are up to 730HP and 950Nm.
Supporting modifications may include:
- Performance exhaust upgrades
- Sports catalytic converter or suitable downpipe
- Performance intake system
- Supporting hardware for the selected setup
Stage 2 tuning depends on the installed hardware, mechanical condition and final calibration. Each setup must be assessed to ensure the modifications are suitable for the vehicle.

Mercedes-AMG G63 W463A Gearbox Tuning
Gearbox tuning can help optimise the transmission’s behaviour and complement the improvements made through engine remapping.
Depending on gearbox compatibility and available software options, transmission tuning may provide:
- Improved gearshift response
- Faster gear changes where supported
- Optimised shift behaviour
- Improved transmission response under acceleration
- Better coordination between engine and gearbox
Gearbox tuning availability and compatibility must be confirmed for the specific vehicle before work is carried out.
Before Tuning
Before carrying out any ECU remapping, we recommend checking that your Mercedes-AMG G63 is in good mechanical condition.
A petrol engine relies on a healthy ignition system, suitable spark plugs and reliable fuel delivery to perform correctly. Any existing engine faults should be investigated before tuning.
Our pre-tuning checks may include:
- Diagnostic fault-code checks.
- Spark plug and ignition system checks.
- Misfire investigation, where required.
- Air intake and boost system inspection.
- Fuel system checks.
- Checking for boost leaks and other relevant engine issues.
- Reviewing the vehicle’s general mechanical condition.
Any issues identified should be addressed before remapping to help ensure the vehicle is suitable for increased performance.
Servicing and Maintenance
Regular servicing is important for maintaining the performance and reliability of your Mercedes-AMG G63, particularly when the vehicle is driven enthusiastically or modified.
We recommend keeping up with routine maintenance, including:
- Regular engine oil and filter changes.
- Checking spark plugs and ignition components.
- Inspecting air filters and intake components.
- Checking cooling system condition.
- Inspecting belts, hoses and other engine components.
- Maintaining the braking system and tyres.
A well-maintained vehicle provides a better foundation for performance tuning.
Exhaust Upgrades
An upgraded exhaust system can complement ECU remapping by improving exhaust flow and enhancing the sound of the V8 engine.
Depending on your chosen setup, available exhaust upgrades may include:
- Performance exhaust systems.
- Sports catalytic converters.
- Suitable downpipe upgrades.
- Exhaust components selected to complement the tuning setup.
Exhaust modifications must be suitable for the vehicle and comply with applicable road-use and emissions requirements.
Performance Upgrades
Supporting performance modifications can help complement your Mercedes-AMG G63 remap and provide a more complete performance package.
Depending on your requirements, possible upgrades include:
- Performance intake systems.
- Exhaust and downpipe upgrades.
- Supporting cooling improvements where suitable.
- Engine and transmission software optimisation.
- Other compatible hardware upgrades.
The suitability of each modification should be assessed against the vehicle’s condition and intended use.
